OSPF
Ada tiga (3) elemen dasar konfigurasi OSPF:
- Enable OSPF instance
- OSPF area configuration
- OSPF network configuration
instance name=default sudah ada, tidak perlu di tambahkan, tapi kalau perlu menambahkan caranya adalah sebagai berikut Catatan: Ingat bahwa backbone area-id adalah 0.0.0.0.
R1:
configure set protocols ospf area 0 network 10.10.1.0/30 set protocols ospf area 0 network 10.10.1.4/30 set protocols ospf log-adjacency-changes set protocols ospf parameters router-id 10.10.1.1
show show protocols commit exit
protocol ospf 10.10.1.1 {
area 0 {
networks {
10.10.1.0/30;
10.10.1.4/30;
}
interface <interface pattern> {
neighbors {
<ip>;
<ip> eligible;
};
};
};
}
R2:
configure set protocols ospf area 0 network 10.10.1.4/30 set protocols ospf area 0 network 10.10.1.8/30 set protocols ospf area 0 network 172.16.0.0/16 set protocols ospf log-adjacency-changes set protocols ospf parameters router-id 10.10.1.6
show show protocols commit exit
R3:
configure set protocols ospf area 0 network 10.10.1.0/30 set protocols ospf area 0 network 10.10.1.8/30 set protocols ospf area 0 network 192.168.1.0/24 set protocols ospf log-adjacency-changes set protocols ospf parameters router-id 10.10.1.2
show show protocols commit exit
